7 studs wide 2-10-4 'Texas' type steam locomotive - real world MOC

[Murdoch17]

This 2-10-4 'Texas' type steam locomotive MOC I have made has two older ancestor LEGO models that were both 2-8-4 'Berkshire' types by other builders. Parts / techniques / ideas from these two models were mashed together to design my own loco.

For the first ancestor loco, we have to go back to 2012, when I bought @SavaTheAggie's 8-stud wide 2-8-4 Polar Express loco instructions. I then spent the next three years heavily modifying the model I made from them, eventually ending up enlarged into a 2-10-4 'Texas' type. This revised loco also had a very similar color scheme to my new loco, with an all-black look with red box on the tender. This original 'Texas' type loco was destroyed long ago for parts. You can buy the original loco instructions by Sava here. 

For the second engine, we move forward to 2021, when I bought some Rebrickable instructions by @Plastic_Goth for a 7-stud wide 'Berkshire', from which I took the boiler and cab areas and made the rest of the loco myself using principles and ideas gleamed from the first loco 9 years prior. this design was modified and used several times in 4-8-2, 4-8-4, 2-8-4, and more wheel arrangements over the years. You can buy the instructions by Plastic_Goth here.

Now in 2025, I have designed a 2-10-4 based on a stretched Plastic_Goth boiler with the paint scheme of my modified 8-wide version of the Sava Railways engine and my own loco running gear + tender. I think I did a really good job mashing these ideas together and making it into my own MOC.

The engine rolls beautifully without any major issues except one: when being pushed backwards the engine can collide with the tender. Grabbing the loco itself and pushing the tender back (instead of dragging the loco behind the tender by holding that) bangs the cab roof into the top of the tender. It's my design's fault, and I can't seem to sort the issue out, unless If making the cab roof shorter in length. (which I don't think looks good and won't be doing.)

The rear of the loco. Apologies for the one tile not being pushed down all the way - it has since been fixed.

The cab of the loco, with firebox and gauges. The engine is 7 studs wide from this point back through the tender, while the boiler is 6 wide, not including the overhang for the walkways.

Thoughts?
